parse to pattern

[snotbubble]

would be useful...

Current behavior:

a: "2. two" b: "" c: charset "0123456789" parse a [ to 1 5 c thru ". " copy b to end ] b
== ""

Expected behavior (same as Red):

a: "2. two" b: "" c: charset "0123456789" parse a [ to 1 5 c thru ". " copy b to end ] b
== "two"

It would be nice for the compatibility reasons, but you can easily get the same result using:

a: "2. two" b: "" c: charset "0123456789" parse a [ to c 1 5 c ". " copy b to end ] b

To implement direct support would be much difficult and I think it would slow down all parsing because of additional checks, so I'm not sure if I want to do it.

Btw... there are some common bitsets predefined in system/catalog/bitsets.. so you can also use:

digit: system/catalog/bitsets/numeric
result: parse "2. two" [
    to  digit
    1 5 digit
    ". "
    return to end
]
;== "two"

understood, will use digit, and marks as a fallback
